My very first app for iPad 1 ..
a double browser that could also be used ... reversed ! year 2010
thanks to this app I got a great understanding of objc swizzle .. it was quite difficult to trick the system to show the keyboard properly oriented, unfortunately its not on the store anymore .. but you can’t forget your first iOS app, can you ? <3
xplode - Unity workshop
It’s always fun to play with Unity3D; this time I was called to explain some of its concepts to a small, but very creative, group of programmers! I hope they enjoyed it. Result is still WIP but WebGL demo is live here.
moon - Middleware chains for Go web applications with Context from x/net/context and http.Handler support
GO is a brilliant language, it encourage the sharing of small libraries with its simple package manager workflow. A middleware is just a function called before the handler of a network request, its goal is to augment/validate or block it before it reaches the final handler. Classic example:
Request IN -> Middleware user session -> Middleware authentication -> Handler -> Response
Each middleware can block the request by writing and returning or move along. Of course for just this behaviour a library is not needed because GO http.Handler can do exactly this by incorporating the handler it should call and by returning an handler that handle the request. Does it make any sense ?
UserSession(Authentication(Handler))) -> http.Handler
and you pass the result to your mix-in (the URLs router), that’s it.
Unfortunately there are 3 problems with the solution provided by the “standard library”:
it’s a mess, the classic example has 2 middleware but usually you have much more (i.e. gzip compression, JSON decode, parameters validation, panic handler)
you have to rewrite all of them for each request handler
it lacks a context that holds partial results that can be passed along and save time and resources (i.e. once you extract the user from the session you may want to keep it till the final handler).
Now there are various super good solutions for all of these, for instance Alice is my favourite for point 2 and there are several good ones for point 3, but none of them mix everything together and this is why moon exists :)
So, help me to earn more STARS on github and share the words :) Moon is a very compact middleware library for GO with 100% coverage that needs some external love, tests and appreciation :) Also Moon is the name of one of my cat and she’s is purring right now next to me, in her cat language it means “this mew library is very good mew, not like your shitty previous ones and I want more food”
Back for some “old school reasons”
I’ve not been a low level C programmer for a long time, but today I was having some fun in the middle of my weekend project of porting an “old” windows CE/KOBO app (LK8000) to iOS and I found something amazing in their code.
Back in the days it was quite common to store data files in the binary executable, I used to append zip files to my exe (zip stores the header at the end of file so I could just unzip my exe and get the content from there) or include binary data in my exe generating C code from a binary dump (you know char my file[] ={0x00…} etc. But today for the first time I saw something amazing :D and I like it so much that I need to share it and use it.
Basically to include multiple resources they simply use an assembly macro that bind the content of the resource file directly inside the .data section. Cool ! I’m amused because there are tons of script that generate a code block but they didn’t use any of them, they just went hard-core and I love it <3
https://github.com/LK8000/LK8000/blob/master/Common/Source/Resource/resource_data.S
.altmacro .macro binfile p q .globl \p&_begin .globl \p&_end .globl \p&_size \p&_begin: .incbin \q \p&_end: /* Put a “.byte 0” here if you know your data is text and you wish to use \p&_begin as a C string. It doesn’t hurt to leave it here even for binary data since it is not counted in \p_&size */ .byte 0 \p&_size: .int (\p&_end - \p&_begin) /* add alias for “_” decorated symname for avoid link error. */ .globl _\p&_begin .set _\p&_begin, \p&_begin .globl _\p&_end .set _\p&_end, \p&_end .globl _\p&_size .set _\p&_size, \p&_size
.endm
.section .rodata
binfile IDR_RASTER_EGM96S “../../Data/Bitmaps/egm96s.dem”
then a C macro create the variables declaration and they just access the data as a ptr*
I love it, that’s it :D of course, llvm didn’t like it, this is my fixed version
.macro binfile .globl $0_begin .globl $0_end .globl $0_size $0_begin: .incbin $1 $0_end: /* Put a “.byte 0” here if you know your data is text and you wish to use \p&_begin as a C string. It doesn’t hurt to leave it here even for binary data since it is not counted in \p_&size */ .byte 0 $0_size: .int ($0_end - $0_begin) /* add alias for “_” decorated symname for avoid link error. */ .globl _$0_begin .set _$0_begin, $0_begin .globl _$0_end .set _$0_end, $0_end .globl _$0_size .set _$0_size, $0_size .endm

iOS extensions using swift
Last year around early September 2014 I created my first custom keyboard for iOS in swift. I remember those days were a debugging nightmare: Xcode couldn’t debug swift and an extension without a improbable macumba of Build/CleanAll/Stop/ChangeSchema/Rebuild/Debug, and the total lack of a managed swift eco system (i.e. using cocoa pods) was hurting me so much; I wasn’t motivated enough and extensions didn’t look a good swift playground so I quit the attempt with an “almost working” iOS custom keyboard and an idea to be resumed in the future.
Almost 8 months later I got back at that idea and found that now an extension can be developed and tested almost like any other app, still there are some traps that have yet to be covered:
Neither cocoa pods (0.37.1) or carthage (stabled 0.6.5, 0.7.4) have been able to create a project that could go from “simulator” to proper “archive and publish” version. Mostly because as soon you pimp your extension with external frameworks these frameworks may not be properly configured for being used by an extension and they require some small tweaks.
This below is my promemoria to achieve a working building system
- let’s say my extension depends on 4 swift frameworks, I don’t have to link them against the extension itself but against the containment app
- whenever possible, avoid frameworks that depends on other carthage frameworks because they may lead to annoying sub carthage dependency with embedded ‘Frameworks’ that need to be cleaned (see below)
- each frameworks must have the following build settings
“Require only API-Extension safe” = YES
“Embedded Content Contains Swift code” = NO **to be honest I don’t understand this **
“iOS Deployment Target” >= 8.0 (some framework may have 7, but extensions must have 8.0 or greater)
- linked frameworks can not contain frameworks as well i.e:
AlamofireObjectMapper depends from both Alamofire and ObjectMapper, using carthage these two dependency are built both inside the AlamofireObjectMapper and externally. Once you submit your app ItunesConnect will complain that this is bad, luckily in this case simply removing the folder “Frameworks” from AlamofireObjectMapper.framework folder itself is enough to fix the problem (anche keep the build working). Note, the same should be valid for other embedded frameworks in frameworks.
In my experience when working with swift and app extensions the most important promemoria has been:
do not just test on device and simulator because the real problems come with distributing the build itself. So before anything works, just create a simply dummy extension project with all frameworks you may need and try to validate it against ItunesConnect. This may save you from replacing code of frameworks not yet ready to be included by an extension (I look at you ReactKit and SwiftKit!)

Ever since I found out that a GCC C extension causes a code block to return a value if you enclose it in round brackets, I’ve been using it in my code. What do you think?
self.bounds = ({ CGRect bounds = self.bounds; bounds.size.height = self.currentYPosition + SHEETINSETY; bounds; });

Let me tell you a thing, about an amazing man named Patrick Stewart
I went to Comicpalooza this weekend and I was full of nervous energy as I was standing in line to ask Sir Patrick Stewart a question at his panel. I first had to thank him for a speech he had given at amnesty international about domestic violence towards women . I had only seen it a few months ago but I was still dealing with my own personal experience with a similar issue, and I didn’t know what to call it. After seeing Patrick talk so personally about it I finally was able to correctly call it abuse, in my case sexual abuse that was going to quickly turn into physical abuse as well. I didn’t feel guilty or disgusting anymore. I finally didn’t feel responsible for the abuse that was put upon me. I was finally able to start my healing process and to put that part of my life behind me.
After thanking him I asked him “Besides acting, what are you most proud of that you have done in you life (that you are willing to share with us)?”. Sir Patrick told us about how he couldn’t protect his mother from abuse in his household growing up and so in her name works with an organization called Refuge for safe houses for women and children to escape from abusive house holds. Sir Patrick Stewart learned only last year that his father had actually been suffering from PTSD after he returned from the military and was never properly treated. In his father’s name he works with an organization called Combat Stress to help those soldiers who are suffering from PTSD.
They were about to move onto the next question when Sir Patrick looked at me and asked me “My Dear, are you okay?” I said yes, and that I was finally able to move on from that part of my life. He then passionately said that his mother had done nothing to provoke his father and that even if she had, violence was never, ever a choice a man should make. That it is in the power of men to stop violence towards women. The moderator then asked “Do you want a hug?”
Sir Patrick didn’t even hesitate, he smiled, hopped off the stage and came over to embrace me in a hug. Which he held me there for a long while. He told me “You never have to go through that again, you’re safe now.” I couldn’t stop thanking him. His embrace was so warm and genuine. It was two people, two strangers, supporting and giving love. And when we pulled away he looked strait in my eyes, like he was promising that. He told me to take care. And I will.
Sir Patrick Stewart is an absolute roll model for men. He is an amazing man and was so kind and full of heart. I want to let everyone know to please find help if you are in a violent or abusive house hold or relationship. There are organizations and people ready to help. I had countless people after the panel thanking me for sharing the story and asking him those questions. Many said they went through similar things. You are not alone.

How to boost your copy GB forever
In the past 3 days I ran two facebook ad to promote my Copy.com referral code.
At the end I spent 57$ to get:
100GB of bonus GB
80 GB waiting for install / email verification (that may never be converted in extra bonus GB)
To be fair with the same amount you can get 250GB for 6 months, but I believe that 100GB forever are a better investment :-)
Campaign details
I started with a "italian" ad to spread copy on my territory, I was quite confident that targeting millions of people with generic interests like "photo upload" would have been ok but that didn't work out.
The first day I basically lost 10$ to "impress 50k" people and get nothing back, the ad frequency was 1.1 and _all_ the 70 clicks I got didn't transform in bonus GB.
For the second day I edited my ad to reach more specific users, I went down from millions of people to just 47k.
This ad targets 47,540 people:
who live in Italy
age 18 and older
who like #Cloud storage, ubuntu one, #Dropbox (service), #Google Docs or #SkyDrive
But as you can read all of them are related to service like copy, and it worked !
The click rate was almost like before but I got an higher frequency (7.1) and what is important people were really interested and registered to the service. At the end of 3 days 18 of 34 people completed all steps.

Since you read all post you deserve the final trick ;) . On FB you can't promote an external url like https://copy.com?r=12345 but it will work if you use an url shortener.
Wow this is not a joke, the same happens on the Italian store. Tnx to @ortwingentz for spotting this out :D
Beware my next AAA game is coming .. guess the name :D
For something very distant from my main programming activity we are organising a workshop about food photography in Florence in the middle of May; since one of my other non-programming passion is photography I joined the organisation team as a kind of "technical director" .. basically I just installed wordpress and got my hand dirty with php :-)
I could start a rant about php, date, strftime and wordpress not calling setlocale .. but now this post is all about the workshop and it would be great if anyone around Florence / Italy on that date would pass by and say hello or just share this post :)
Thanks for you support !!
Must have Xcode inline plugins
1) https://github.com/ksuther/KSImageNamed-Xcode
Damn me! I've been dreaming of this plugins for years .. why ? it auto completes and preview the images when you write
[UIImage imageNamed:....]
2) https://github.com/omz/ColorSense-for-Xcode
Like the previous one but this one works with colors (btw do you know I love paintcode ?)
3) https://github.com/questbeat/Lin
So what about localizations ? here we go! basically this plugin auto completes the NSLocalizedString keys and on top of that add a simple string editing functionality.
Just a side note: it works great with genstrings-ed files based on *.m but its a bit annoying to browse all the random keys generated by turning on XCode 4.5 "Base internationalization" on .Storyboard and .xib
4) https://github.com/garnett/AutoresizeMask-for-Xcode
Getting confused by the autoresize mask enums ? no more ! a little preview popup makes them obviously clear.
Embedded in the game is a classic immigrant story. Mario and Luigi are Italians in a strange land, blue-collar workers who travel back and forth between an above-ground mainstream and various undergrounds, moving through worlds (or class strata?) accumulating stuff, strength, and respect, all in a quest to get to a big house where they’ll liberate a beautiful woman — the final stage of the class-passing dream. Along the way, they hustle and fight and scrape to collect artificial performance enhancers (mushrooms, fire flowers) and currency (all of which can extend their lifelines), banging their heads against rocks to get ahead. They quickly learn the only thing more important than timing is artful cheating: With the prevalence of warp zones, shortcutting the system is part of the superstructure. As the landscape becomes more treacherous and competition more fierce, they find that they can no longer survive without the “boost” of mushrooms and invincibility stars. In the final stages, they race against the clock in abject desperation, roided-out addicts making stupid, careless mistakes in their frenzy to ascend just one more level. Maybe they find and save the princess in the end, but at what cost? It could be a lost Godfather sequel. It could be Scarface.
The Strange Case of the Super Mario Bros. Movie - Grantland (via Jason Goldman)
I have a longstanding fondness for tales of moviemaking disaster (“Hearts of Darkness,” about the torturous production of “Apocalypse Now,” is one of my all-time favorite documentaries), and this article about 1993’s shockingly clueless/soulless film adaptation of “Super Mario Bros.” is a great one. I particularly like the above attempt on the author’s part to put herself in the shoes of one of the film’s succession of non-gamer screenwriters and extract a film-able narrative from the game. I often play the same game of “armchair script doctor” when I’ve just seen a particularly shoddy adaptation of something.
(Update: Briana points out that this synopsis could almost match “Requiem for a Dream”)
